General Information
Term decreased cell number ID (Ontology) FBcv:0000359 (FlyBase CV)
Definition Phenotype that is a decrease in the number of cells in a whole animal or in some specific organ, tissue or clone of cells compared to wild-type. This phenotype is not necessarily accompanied by decreased growth - there may be fewer cells in an otherwise normal volume of tissue.
Also Known As"reduced cell number"
